GUTTE-R AND ROOF-SUPPORT Fo'R GREENHOUSES.

SPECIFICATION forming part of Letters Eatent No. 737,110, dated August25, 1903.

I Application filed April 17. 1903. Serial No. 153,147. (No model.)

To all whom, it may concern:

Be it known that we, WILLIAM 0. JOHN- STON and PHILIP J. FOLEY, citizensof the United States, residing at Chicago, in the county of Cook andState of Illinois, have in-' vented a new and useful Gutter and Roof-Support for Greenhouses, of which the following is a specification.

Our object is to provide a new form of metal gutter for greenhouses, tofacilitate fixing tubular posts thereto for supporting the gutter, toadapt the gutter for advantageously fixing sash-bars thereto, and toconvey water of condensation from the sashbars into drip-conductors atthe parallel sides of the gutter.

Our invention consists in the construction, arrangement, and combinationof parts,.as hereinafter set forth, pointed out in our claims, andillustrated in the accompanying drawings, in which Figure 1 is atransverse sectional view of the gutter and drip-conveyors and shows themanner in which tubular posts are detachably fastened thereto andsash-bars fitted to the top and side of the gutter at any pitch or angledesired and securely fastened by means of screws passed through lugs onthe gutter into the wooden-sash-bars. Fig.2 is a transverse sectionalview of a sash-bar.

Fig. 3 is a side view of the drip-gutter and is a transverse sectionalview on the line 03 a;

of Fig. 1 looking downward.

The numeral 10 designates the metal gutter, that is preferably cast in amold. It is obvious it may vary in size and weight as desired and inlength of sections. It has integral tapering fiat lugs 12, projectingdownward in alinement with the longitudinal center of the bottom of thegutter at points where supports are tobe connected therewith andprovided with bolt-holes for fastening clamps to the lugs and gutter, asrequired for detachably fixing posts to the gutter. At its parallelsides are integral drip,-

. conveyors 13, and at the points where sashbars are to be fixed lugs 14are formed on or fixed thereto and provided with transverse slots,through which screws can be passed into sash-bars, as shown in Figs. 1and 2.

The parts 15, that extend from the top edges ofth'e gutter 10 forconnecting the drip-conveyers 13 and for supporting sash-bars, arecurved to serve as arcs of true circles for concentrically fitting andfixing the ends of sash-bars-thereto, so they can be extended atdifferent angles, as required to produce such a pitch of roof as may bedesired. Grooves 16 in the metal can be advantageously filled withcement for making water-tight joints where glass'terminates at the lowerends of sash-bars 17, fitted and fixed to the gutter, as shown inFig. 1. Grooves 18 in the side faces of the sash-bars convey water ofcondensation from the bars into the drip-conductors 13.

Clamps 20, fitted to the under side of the beveled and bent inward andfitted to the clamps. Ooinciding perforations in the clamps and the fiatlugs 12 admit a screw-bolt 23 for detachably fixing the parts togetherby means of a nut on theend of the bolt.

Having thus set forth the purpose of our invention and the construction,arrangement, and combination of the diiferent parts, the

practical utility thereof will be readily understood by persons familiarwith the art to which it pertains.

What we claim as new, and desire to secure by Letters Patent, is-

1. In combination with a metal gutter for greenhouses having a flat lugprojecting downward from the longitudinal central line of the bottom ofthe gutter and provided with a bolt-hole, a pair of clam pingrirons, asshown and described for the purposes stated.

2. A metal gutter for greenhouses having an arc portion extendinglaterally at its top and side, a drip-conveyer extending downward fromsaid are portion and a lug extending upward and outward from thedrip-conveyer, for the purposes stated.

3. A metal gutter for greenhouses having are portions extendinglaterally at its top and side a drip-conveyer extending downward fromsaid arc portions and a lug extending upward and outward from thedripconveyer and a sash-bar fitted to the arc portions and fixed to thelug and gutter and provided with grooves in its side faces, arranged andcombined in the manner set forth for the purposes stated.

4. A metal gutter having a Hat lug projecting downward from its bottom,clampingirons fitted to the said fiat lug and gutter, a screw-boltextended through coinciding apertures in the said fiat lug and saidirons and the lower end portions of the said irons adapted to contactwith each other and provided with shoulders to engage the top of atubular post and downward extensions adapted to enter and engage thepost, in combination with a tubular post, for the purposes stated.

5. An improved gutter and sash-bar and gutter-support comprisinga metalgutter having flat lugs projecting downward from its under side, arcsextending outward and downward from the tops of its parallel sides,dripconveyers below the arcs, lugs extending upward and outward from thedrip-conveyers, sash-bars fitted to the arc portions and fixed to thesaid lugs and provided with grooves in their side faces, clamping-ironsfixed to the said flat. lugs to extend into the tops of tubular postsand provided with shoulders to engage the tops of the posts, arrangedand combined in the manner set forth for the purposes stated.
